1 BASKETBALL REBOUND DOME This application is a continuation-in-part application of our pending application Ser. No. 8 I 8,572, filed Apr. 23, 1969, now US. Pat. No. 3,795,401.

This invention relates to attachment devices for game equipment, and more particularly to a device for basketball practice.

It is therefore the main purpose of this invention to provide a basketball rebound dome which will be at'- tached by clamp means to a basketball hoop and will serve to develop basketball players rebound ability with a basketball.

Another object of this inventionis to provide a basketball rebound dome which will be moulded or formed in a suitable way so as to have up-raised hemispherical surfaces, which when the basketball strikes one of these surfaces, it will causethe basketball to rebound in a random fashion. I 1

A further object of this invention is to provide a rebound dome of the type described, which will have a plurality of clamp members secured to. the rim of the device to clampingly engage the hoop attached to the backboard so as to render the dome device stationary while also allowing it to be easily removed after a practice.

I dome has a single bump thereon of hemisphericalcon- Other objects of this invention are to provide a bas-' ketball rebound dome which is simple in design, inexpensive to manufacture, rugged in construction, easy to use and efficient in operation. 7

These and other objects will become readily apparent upon a study of the following specification together with the accompanying drawings wherein? FIG. 1 is a perspective view of the present invention I shown. secured to a basketball hoop with a basketball shown in phantom lines; 7

FIG. 13 is afragmentary perspective view of the invention wherein the bumps are upstanding, triangular prisms; I

FIG. 14 is a'fragmentary perspective view wherein the bumps are upstanding, hexagonal projections;.

FIG. 6 is a fragmentary perspective view of the invention wherein the bumps are upwardly projecting, cylindrical prongs; V

FIG. 7 is a fragmentary perspective view of the invention wherein the. bumps are elongated triangularshaped prisms;

FIG. 8 is a fragmentary perspective view of the inven- 55 tion wherein the bumps are cones;

FIG. 9 is a fragmentary perspective view of the inven tion wherein the bumps are of a faceted configuration having a plurality of sides;

In FIG. 8 the bumps are cones.

- In FIG. 9 the bumps 32 are of a faceted configuration I of many sides. 1

In FIG. 10 the convex upper outer surface 360f the.

rebound dome is of irregular configuration. I

In FIG. 11, the convex outer surface 40has aplurality of bumps 41 thereon of irregular configuration. I

In FIG. 15, the convex'outer surface hasa single I posihemispherical bump '52 thereon, which 'may be tioned anywhere on such surface 50.

In FIG. 16, the convex outer surface 54 hasa plurality of different type bumps thereon such as the prong 26, the cone 30 and the pyramid 24.

In essence, the invention contemplates the use of any type or shape of bumps positioned in irregular or in 1 symmetrical pattern on the convex outer surfaceuFor example, the bumps-28 of FIG. 7 are positioned on-the convex surface member in substantially symmetrical j In FIG. 6, the-bumps'26 are upwardly projecting 1 In FIG. 7 the bumps 28 are elongated triangular upstanding rectangular 1 i bumps 48 are upstanding hexagonal pattern, and the bumps 41 of FIG. 11 are disposed on the convex member in irregular pattern.
